Mizuno MP-20 Irons

The most noticeable change in the MP-20 is the re-introduction of copper underlay between the Grain Flow Forged heads and chrome plating. Last seen in Mizuno’s much-revered MP-29, MP-14, and the legendary TN87 – copper underlay was originally used to adhere the chrome plating to forged steel. Re-introduced in Japan’s domestic Mizuno Professional line in 2017, testing suggested that the legendary feel of the older blades was most likely due to that layer of copper.
